Cumulative reward meaning
WebAug 29, 2024 · Reinforcement Learning (RL) is the problem of studying an agent in an environment, the agent has to interact with the environment in order to maximize some cumulative rewards. Example of RL is an agent in a labyrinth trying to find its way out. The fastest it can find the exit, the better reward it will get. The cumulative reward at each time step t can be written as: Which is equivalent to: Thanks to Pierre-Luc Bacon for the correction. However, in reality, we can’t just add the rewards like that. The rewards that come sooner (in the beginning of the game) are more probable to happen, since they are more predictable … See more Let’s imagine an agent learning to play Super Mario Bros as a working example.

WebFor this, we introduce the concept of the expected return of the rewards at a given time step. For now, we can think of the return simply as the sum of future rewards. Mathematically, we define the return G at time t as G t = R t + 1 + R t + 2 + R t + 3 + ⋯ + R T, where T is the final time step. It is the agent's goal to maximize the expected ...
